Today's Weather Trivia

25 May

1919: The Cassandra carrying 400 passengers between Montreal, QC, and Glasgow, Scotland, struck an iceberg 300 km off Cape Race, NL, and had to turn back. Several plates below the waterline on the starboard side were crumpled by the low-lying berg. Passengers were escorted to the deck safely with only slight confusion. On approaching St. John’s, NL, the boat was further stopped by heavy all-night fog.
